In my Spacemacs, I enabled the spell-checking layer which enables ispell. I noticed that my Tramp connection is very slow, and after debugging, I found that one of the causes is ispell:
02:07:20.446250 tramp-do-file-attributes-with-stat (5) # file attributes with stat: /path/to/.ispell_words
....
....
....
....
02:07:23.961344 tramp-send-command (6) # test -r /path/to/.ispell_default 2>/dev/null; echo tramp_exit_status $?
So about 3 seconds are wasted on ispell. I tried disabling the spell-checking layer and found that Tramp is indeed faster.
However, I don't want to totally disable spell-checking, as I in fact use it frequently when editing locally. Is it possible to disable ispell only when I use Tramp? Thanks!
flyspellis active (runningaspellor other equivalent), so you are potentially dealing with several buffers at issue. I encountered problems when runningflyspell(i.e., anaspellrunning process) and other programs, although not necessarily tramp. I ended up modifying theflyspell/ispelllisp libraries to turn on/off after the words have been checked in the current command loop. The disadvantage with my solution is that re-reading custom words, depending on the length of the list, could slow..aspell(orhunspell) from running all the time; e.g., to run only when checking a word during the current command loop and then disengage: debbugs.gnu.org/cgi/bugreport.cgi?bug=32610 Eli Z. opined that this was not desirable by most users and he stated a few reasons. I did not, however, advise Eli Z. of problems that I experienced when other programs were active as a running process. [I hacked my own on/off ...]
